Gets hot and stalls out

There is a thin insulated gasket/spacer you can buy.
However before buying parts, determine the source of the the problem.
A carb spacer will not solve heat issues in the feed line.

Fuel filter angle looks good.

You can do a bunch of investigating. When it won't start, take the air cleaner off. Is there fuel dripping (over filled bowls)? Open a siyte plug to check levels. (have a rag ready). One reason it won't start is flooding (vapor pushed extra fuel into the bowls) and the other is vaporization in the carb (not enough liquid fuel - or not enough of the light molecules still in liquid state). Different causes = different solutions

Measure the timing. Get the coolant temps down and the engine bay temps may go down. Find out if you're area has winter fuel - that makes things worse - much worse. Etc etc.

Thank you - great advice. I see there's a .250 spacer; I'll start with that. I'll switch the fuel lines from the pump to the carb to SS, and heat-shield them. (Any thoughts from the forum about shielding the fuel rail as well?) That should drop the fuel temp considerably. I do think getting an IR gun and checking the inflow/outflow of the radiator as well as the difference in temps on the fuel line after they're shielded would be good data to have. Also getting the timing data and referring it here so I understand it will add to the data.

Again, the car stalled AFTER it was shut down for a few minutes and then re-started (attempted re-start), meaning the temps climbed significantly over those few minutes. I did not see any fuel dripping from the bowl but you could certainly smell it, so based on this one incidence I think it's more of a vaporization issue than flooding. I think getting the fuel to the carb cooler is a good first step, but after I do all of that I want to address the overall engine temps with a goal of 190* in start-stop traffic on a reasonably warm (95*) day. I don't drive it much if it's hotter than that just because the car does not have A/C. Based on the various opinions on the forum, the radiator is likely sufficient, but I likely need to address the fan, pump and thermostat. These fixes should also give me an indication if there's any electrical issues that need to be addressed.

There's my plan. Any input is greatly appreciated.
